Second Brain & Personal Knowledge Management Test

The Second Brain & Personal Knowledge Management Test is a free beginner-level, 15-minute skill test from Science of Apps. It tests personal knowledge management (PKM) and the "second brain" — capturing ideas, the CODE method of capture, organise, distil and express, the PARA system of projects, areas, resources and archives, progressive summarisation, the Zettelkasten method of atomic, linked notes, fleeting, literature and permanent notes, bidirectional links and backlinks, tags versus folders, tools such as Obsidian, Notion and Logseq, task management and weekly reviews, spaced repetition, avoiding the collector's fallacy, and privacy, backups and portability — written to Forte Labs, Zettelkasten.de and learning-science research for 2026 and 2027. Score 70% or more on its 15 questions to earn a verifiable Second Brain & Personal Knowledge Management certificate (SOA-SBPK). Every question is based on published standards and research — including Building a Second Brain and the PARA method (Forte Labs (Tiago Forte)), Introduction to the Zettelkasten method (Zettelkasten.de), So Much to Read, So Little Time: How Do We Read, and Can Speed Reading Help? (Rayner et al., Psychological Science in the Public Interest (2016)) — and each answer is explained with its source.
